Abstract

The invention discloses a double-V-shaped-block parallel synchronization lifting mechanism which comprises a hand wheel, bevel gears, a right rotating lead screw, a left rotating lead screw, a lead screw guiding sleeve, a lead screw guiding rotating stopping flat key and the like. A first bevel gear is fixedly arranged at the end of a hand wheel rotating shaft and is meshed with a second bevel gear arranged on a supporting plate. One end of a spline telescopic joint sleeve transmission shaft is fixedly provided with a third bevel gear which is meshed with the second bevel gear, and the other end of the spline telescopic joint sleeve transmission shaft is fixedly provided with a fourth bevel gear which is meshed with a fifth bevel gear. The two lead screws which are the same in lead and opposite in rotating direction are screwed on the second bevel gear and the fifth bevel gear through lead screw nuts which are placed at the circular centers of the second bevel gear and the fifth bevel gear and are integrally machined with the two bevel gears respectively. The upper ends of the two lead screws are respectively provided with a V-shaped block. According to the double-V-shaped-block parallel synchronization lifting mechanism, the bevel gears are driven by rotating the hand wheel, then the lead screws drive the two V-shaped blocks to move up and down synchronously, fine adjustment effect is good, accumulative errors are avoided, the force increasing ratio of the whole mechanism is large, and the hand wheel is convenient to use.

Description

technical field [0001] The invention belongs to the field of mechanical engineering, and in particular relates to a parallel synchronous lifting mechanism of double V-shaped blocks. Background technique [0002] For machines such as honing machines, cylinder cleaning machines, etc., which use the main shaft as the execution element to process the inner surfaces of cylinder-type workpieces with different diameters, the machine spindle and the workpiece axis need to maintain a certain degree of coaxiality. Usually, the V-shaped block is selected as the positioning element of the cylindrical cylinder, and the height of the V-shaped block needs to be adjusted frequently to adapt to the change of the center height due to the change of the bore diameter of the workpiece, so as to ensure that the center of the cylinder and the center of the machine spindle are always in the same position. the same height. [0003] The existing equipment generally adopts two sets of V-shaped block ...
